I just got the APR exhaust installed on my b9 s5 Sportback a couple days ago and im pretty disappointed. Cruising in comfort mode it drones like crazy on the highway but then at WOT in dynamic it’s quiet. I tried reaching out them and haven’t received a reply but guys I need help lol. I’m not sure what adjustments I can make to this exhaust to improve the sound and drone because now the pops and burbles are gone from when I had just the front resonator delete on stock exhaust. I’m stock tune as well I was planning on going stage 1 with either 034 or IE. I need some suggestions any input helps
